Euglena Co., Ltd. (Headquarters: Minato-ku, Tokyo; President: Mitsuru Izumo) presented its latest research and practical case studies on the use of microalgae as feed at the symposium 'Utilization of Microalgae for Sustainable Fisheries' (organized by Sosuke Imamura, NTT; Kentaro Ifuku, Kyoto University), held at Doshisha University on March 10, 2026, as part of the Japan Society for Bioscience, Biotechnology, and Agrochemistry (JSBBA) publicly solicited theme symposia. The company demonstrated directions for contributing to the realization of sustainable primary industries through growth promotion and immunity improvement in the fisheries, livestock, and agricultural sectors.
### Background
The environment surrounding the agriculture and fisheries industry is becoming increasingly complex due to global warming, livestock infectious diseases, dependence on imported feed, and a decrease in producers and labor. In response, Euglena Co., Ltd. is creating new feed and fertilizer models utilizing microalgae cultivation technology based on its 'Biomass 5F' business strategy (Food, Fine Chemical, Feed, Fertilizer, Fuel). In June 2025, the company launched the Euglena-derived feed and fertilizer brand 'Ikimono-tachi ni Euglena' (Euglena for Living Things) to accelerate social implementation through both R&D and consumer awareness.
### Overview of the Presentation
As part of its efforts toward sustainable primary industries, the company introduced the following research results and progress in social implementation regarding the use of microalgae like Euglena as feed and fertilizer.
#### Potential of Microalgae Euglena and Research Results in Various Fields
Euglena is characterized by its rich 59 nutritional components and the functionality of its unique component, Paramylon. It has been confirmed that these nutrients and functional components promote healthy growth and contribute to improved immune function in both animals and plants. Unique properties such as lack of cell walls for easy digestion and oil accumulation also suggest potential for wide application as feed and fertilizer. Furthermore, Euglena produced by the company has obtained the ASC-MSC Seaweed (Algae) certification, an international standard for responsibly produced seafood.
- **Aquaculture:** In joint research with the Faculty of Fisheries, Kagoshima University, feeding trials with Euglena-supplemented feed for amberjack and kuruma prawns showed no negative impact on growth. Amberjack exhibited increased blood lysozyme activity (an innate immunity indicator), and kuruma prawns showed increased total phenoloxidase activity involved in infection defense. These results indicate that feeding Euglena can contribute to reducing disease risk in farmed products.
- **Livestock:** Feeding trials in chickens confirmed growth promotion, improvement in feed conversion ratio (FCR), and an increase in specific antibody titers, suggesting contributions to both immunity and productivity.
- **Agriculture:** In the agricultural field, several positive effects derived from soil environment improvement have been confirmed, such as increased fresh weight in Mizuna and extended flowering periods in Petunias.
### Branding of Produced Goods
To connect research results to social implementation, the company launched a system in 2025 to certify agricultural, livestock, and marine products raised using Euglena-derived resources as 'Euglena Sodachi' (Raised with Euglena). Diverse products have already emerged, such as 'YES Buri' (farmed fish) in fisheries, 'Nagomi Tamago' (eggs) in livestock, and 'Pikamaru' (rice) in agriculture, with awareness spreading through collaboration with producers. This branding mechanism aims to create added value for producers and consumer interest.
